It's rude to me as well. But I think we are wrong about this.

I was in the doctor's office and a person was on the phone talking in the waiting room. I thought it was weird. But then I thought "if a person was sitting in the seat next to them and they were talking, would that be weird?"

I don't think we'd see two people talking as being weird. Why is it weird if someone is by themself speaking to someone that isn't around on the phone? If two people can speak in that place, it's not weird for someone to have a phone discussion.

Now playing music speakers or watching TikTok videos on your phone in a public place...psychotic!
